Application filed June 3, 1909. Serial No. 499,933.

To all whom it may concern:

y -Be it known that we, McCLINToCK YOUNG and HARRY J. LEnnEnz, citizens of the `United States, and residents of Frederick, yin the county of Frederick and State of y'ing the backs and applying the tufts thereto shall be expeditiously eiiected.

A further object is to provide for the efficient cleaning and trimming of the bristles after they have beenV applied to the backs.

In the present form of embodiment of "our invention we employ a traveling conveyer by means of which the blocks, constituting the backs, are transported in a fixed path, a series of drills arranged in succeeding order, and a corresponding series of tuft inserting devices also arranged in succeeding order, said drills and devices being adapted res ectively to bore the holes in the backs an insert the tufts or bristles therein, to-

gether with rotary trimming and rotary cleaning devices to which the brushes are progressively advanced 4by the conveyer in a manner to trim and clean the bristles.

The invention also includes various features of construction and combination of parts, all of which will be hereinafter described and claimed.

Fig. 11 is a face view of the pin wheel element of the conveyer actuating gearing. Fig. 12 is a partial plan of the series of drills, showing their relation to each other and to the ath of-the brush blocks. Fig. 13 is a simi ar plan of the series of tuft inserting devices. Fig. 14 is a view, similar to Fig. 10, of a modification wherein the drills are disposed in line with each other.

l designates the main frame, including in its construction the bed 2 and standards 3; and 4 is t-he main driving shaft suitabl journaled in bearings in the standar s and provided with the fast and loose pulleys 4, et, respectively. Supported longitudinally upon and above the bed, and in parallelism with each other, are two bars 5, the ends of which project beyond the bed. These bars are conveniently provided with brackets or feet which are bolted to the bed, the bars being uniformly spaced or separated to afford between them a longitudinal runway for the upper horizontal stretch of a conveyer G. Thls conveyer passes around suitable wheels 7 the shafts of which have their bearings in brackets or hangers depending from the ends of the bars. The conveyer in its preferred form is composed of a series of links or sections jointed together at their ends to constitute a fiexible endless chain. The links are provided with laterally disposed ribs Sand the inner sides of the bars are equipped with longitudinally grooved rails 9 with the grooves of which the ribs 8 register as the conveyer passes along the runway. Thus the upper stretch ofthe conveyer-is efectually supported and guided in a horizontal pat The inner faces of the links are provided with gear teeth 10 with which meshes a gear wheel 11 mounted to turn within the space between the rails. ried by a transverse shaft 12 (Figs. 1, 9 and 10), which has its bearings in two of the supporting brackets of the rails, and in a bracket 13 on the bed plate. The shaft is given a variable intermittent motion, as

This wheel is car-- .conveyen sion.

hereinafter described, in a manner to effect a corresponding advancement of the 'con Yeyer. The links are provided at their forward or leading ends with outwardly rojecting lugs 14 which constitute in e ect jaws, the distance whereof between adjoining links corresponds with the length of-a brush back or block or substantially so. At one end of the runway is a vertical hopper 15 within which the selected brush backs or blocks are piled, one upon another, the lowermost back resting upon the ccnveyer between the jaws of adjoining links. (See Fig. 7 At this point the jaws are open or divergent by reason of the flexing of the links while they are passing around the proximate guide wheel, but as the links assume a horizontal path the jaws are brought into parallelism With each .other and thus caused to grasp the interposed back and carry it onward with the Another back is then delivered by the hopper to the succeeding link of the conveyer, and so on in continuous succes- The backs are thus carried in endwise procession through the runway.

During the travel of the backs or blocks they are presented to drilling mechanism A by means of which transverse rows of vertical holes are drilled in their upper surfaces, and then to tuft-selecting and inserting mechanism B by means of which tufts of liber are selected and inserted into respective holes.

Referring to the drilling mechanism-16 represents a series of vertical drills corresponding in number with the holes in a transverse row. In the present instance, there are four holes in a row, and hence four drills are provided. These drills are mounted and .arranged in succeeding order to act in different vertical planes corresponding with those of a row of holes to be formed in the brush back, whereby, as the backs are intermittent-ly advanced beneath the drills, the first drill acts to form the first or end holes of the consecutive rows, the next the second holes thereof, the next the third holes, and the next the fourth or end holes. Thus when each back has passed the fourth drill, the back has its full quotaof holes for the reception of the tufts of fiber.

While the distance horizontally between the vertical planes of succeeding drills may be equal to the space between the hente'rs of adjacent Aholes of a row, and the backs be fed in a. straight path below the same, yet

we prefer to reduce the extent of horizontal projection of the succeeding drills and compensate for the reduction by feeding the backs at a slight angle in respect to the vertical paths of the drills, as illustrated. This cooperative relation of the succeeding drills to the travel of the backs may also be secured by disposing the drills in alinement with' each other, and by feeding the backs at a proper angle thereto, as indicated in Fig. 14.

The drill devices herein selected to illustrate our invention are, aside from their peculiar mounting in multiple', generally of the character shown and described in Letters Patent of the United States, No.

"578,907, dated March 16, 1897. They may be briefly described as follows The drill spindles 17 are journaled in heads carried by brackets18 affixed to a frame bar 19 supported by end posts 20 rising from the bed. Each of the spindles is provided with a pulley 21 which is' connected by a belt 22 with a pulley 23 on a' spindle and its drill are lowered and raisedat the commencement and completion, respectively, of each drilling operation.

The shaft 29 is provided with a sprocket wheel 30 which is geared with and driven by a corresponding sprocket wheel 31 on a supplemental drive shaft 32 by means of a chain 33. This supplemental shaft is provided with a pulley v34 which is connected by means of a belt 35 with a pulley 36 on the main drive shaft.

The endless conveyer 6 is advanced with a series of uniform intermittent movements corresponding with the numbers of rows of holes to be formed in the brush back, and

at the end of each series the conveyer isgiven a movement of somewhat greater eX- tent in order to compensate for the spaces between the ends of adjoining` backson the conveyer. Duringeach dwell of thel conveyer, the drills are lowered to bore the holes therein and then raised preparatory to a' succeeding operation. While any suitable mechanism may be employed .to impart the required intermittent movements to the conveyer, we prefer to employ rcam and pin wheel devices of the character shown in Figs. 9, 10 and 11, as follows z--Aflixed to the outer end of the transverse shaft 12, is a wheel 37provided on its outer face with two series of pins 38, each series corresponding in number with the rows of` holes to be formed in the brush back. The pins are unif formly spaced apart, excepting the first and final pins of the respective series, the distance letween which represents the long movement to the wheel.

space movements ends of adjacent backs. shaft. 32 is a worm or acting surfaces 39, 40, the former of whichprojects beyond and is, of less pitch than the other, whereby in the rotation of the cam its surface 39 engages the shortpins successively and imparts the series of uniform intermittent movements to the wheel, and upon the completion of such series of movements the surface 40 engages the lc 1g pin and imparts. the extended' or long space This being done, the cam surface 39 re'ngages the short pins and the uniform feeding operation is repeated, andso on.

' and along the the magazine -for l Referring to the tuft-selecting and inserting mechanism,41 represents a' series of fiber-containing'hoppers supported at intervals along t-he bed; 42 a corresponding series of tuft inserting devices; and 43 a correspondin series of 'reciprocating tuftselectingV -sli es which in their operation select tufts of fiber from the respective hoppers and transfer them to and beneath the respective drivers for insertion thereby into the previously bored holes of the underlying brush backs.

The tuft `inserting devices include the drivers 42arranged at different points-above trackway, and in the same relative the drills, to the end that as the bored bac'ks are intermittently moved beneath the drivers, the first driver acts to insert tufts successively into the first or end holes of the consecutive rows'; the next driver to insert tufts into the second holes; the next into the third holes, and the next into the fourth or end holes. Hence when veach passed the fourth or finaldriver all the holes ofthe back are fully supplied with tufts of fiber. (See Fig. 13.)

The tuft-selecting and inserting devices herein selected to illustrate our invention, are, aside from theirpeculiar mounting Ain multiple, generally of the character shown and described in Patent No. 578,907, hereinbefore referred to. Briefly described, each of the slides 43 is'connected byl means of a link 44 with the lower. arm of a lever 45 carried by a rock shaft 46 the upper arm of which lever is provided vwith a' block or roller in engagement with a cam 47 on a driven shaft 48, whereby the slide is periodically reciprocated to move the notched fiber-receiving port-ion of the slide under a supply of fiber, and then beneath the fiber-guidmg and seatingV devices to transfer the ber to a position below the latter. The shaft 48, similarly to the shaft 29, is provided with sprocket wheels 49, which are connected with sprocket wheels 50 on the shaft 32 by means of chains 50.

The slide 43 bears on its side a relativelyposition to the path of the backs as` movable plate 49 which during the reciprocation of the slide is actuated periodically to open and close the lfiber-recelving notch ofthe slide.

The vertically-reciprocating driver 42 in its descent engages the opposing wisp of fiber and forcibly inserts'it into the underlying hole in the brush back. The driver 1s carried-by a slide 42 which is connected by means o f a link 51 to one arm of a lever 52 the other arm of which is joined by means of a link 51 with a crank arm 53 on the shaft 48 and. thereby vertically reciproy cated. The driver not only inserts the tuft or wisp of fiber into the hole in the brush back but also seats and drives into the back the wire staple for fasteningr the tuft. The wire from which the staples are formed, is fed as usual from a suitable reel R to clamping and cutting devices adjacent the driver, the clamping devices carrying the severed wire for the staple and being periodically moved beneath the driver by a vibrating lever 54. This lever is mounted on the outer end of a rock shaft 55 having its bearings in a bracket on the bar 19, 'the inner end of the shaft having a crank 56 which enters a cam 57 bn the shaft 48, substantially as set out in the Patent No. 578,907 aforesaid. Separate wirel reels R are provided for the inserting devices, and these reels are conveniently mounted on suitable supporting bars projecting rearwardly from the main frame. In-

stead of the sliding member shown and described in said patent for aiding in forming the tuft and guiding it to the brush back, Wepreferably thou h not essentially employ the oscillatory mem er herein illustrated, t-he same comprising a longitudinally channeled head 58 affixed to one end of a horizontal rock shaft 59 and thereby movable into and from the .vertical path of the driver 42. The other lend of the shaftV 59 is connected by means of an arm 60 with one of the arms of a crank lever 61, the other arm of which is connectedy by means of a link 62 with a lever arm 63 on the rock shaft 46 whereby during the descentof the driver the guide head 1s maintained in a vertical position to receive' the same, ,and then upon-the insertion of the tuft is swung laterally to escape the vtuft and permit the unobstructed advaneev of the brush back. In the resent instance two shafts 48, are employe ,j each carr ing the cams and crank arms for two of t e tuft selecting and inserting mechanisris. If desired, a single shaft may be use When the brushes leave the tuft inserting mechanism, and before they are discharged from the conveyer, they are advanced under and are subjected to the successive actions of cleanin and trimming mechanisms, C, D, res ectlvely, which are preferably of the fol owing description:

64.- is a bracket aiiXed to the main frame at or adjacent the discharging end of the run Way. Journaled in suitable bearings in this bracket are tvvo parallel shafts, 65, 66, the inner ends of which overhang the runway -and bear a cleaningwheel 67 and a cutter head 68, respectively. The opposite ends of these shafts are equipped with pulleys 69, 70, which are connected With and `driven from pulleys 71, 72, on the main drive shaft by means of belts 7 3, 74, respectively." The cleaning Wheel is peripherally studded With Wires or pins 75 Which rapidly rotate in the path of the upwardly-projecting tufts or fibers of the underlying brushes and thereby lthoroughly beat out and remove the freeor loose fibers.

The cutter head is provided with radial cutter blades 76 which are arranged tocoact- Witha relatively fixed cutter blade `77 in the path of the free ends of the fibers, and thereby eificiently trim off the irregular ends to insure a uniform fibrous surface for the brush. The'blade 77 is aflixed by screws or other means to an overhanging bar 78 projecting from the bracket 64.

When the conveyer passes around4 the sprocket Wheel at the discharging end of the machine, the jaws 14 of the conveyer'links open or diverge to permit the finished brushes to fall therefrom into a suitable receptacle.

While we ,have herein shown and de,- scribed a simple and efficient form of embodiment of our invention, it is -to be under stood that we do not limit ourselves thereto, as the mechanism may be modified in many respects without departing from the fair spirit of the invention.

We claimy 1. The combination with a series of tuft' inserting devices arranged in succeeding order and correspondin` in number with each transverse row of tu s to be applied to a brush back, of means for feeding backs progressively to said devices.

2. The combinationl With a series of tuftinserting devices arranged i1. succeeding order and corresponding in number with each transverserow of tufts to be applied to a brush back, of means for feeding backs in,
